4.7 Thermistor
The thermistor is very important to adjust the strobe time (Tstrobe) ~ (SLT) in function of the head temperature and
to monitor the temperature to prevent the head damage if the temperature is over the limit described in the
Maximum conditions table.
Resistance R25: 30 KW ± 5% at 25°C •
B value: 3950 K ± 2% •
Operating temperature: –20 ~ + 80°C •
Time costant: Max. 30 sec.(in the air) •
Then the resistance value, R, versus temperature , T (in °C) is given by the formula:
R(T) = R25 × e { B × (1/TX – 1/T25) }
